HAMMOCK is a research study that explores how gay and bisexual men use drugs at private parties in Bangkok, Thailand. Researchers want to understand the health risks involved โ including risks around substance use, sexual health, mental health, and infections โ so they can develop a new support model that keeps people safer. The study includes conversations with party hosts, guests, community organizations, hospital workers, and police.
Drug use at private parties can create serious health and safety risks, but there is little research into what's actually happening or how to help people stay safe. This study exists to fill that gap and create practical, realistic approaches to harm reduction that work in real-world party settings.

Depending on your role, you would complete a self-administered questionnaire or participate in an in-depth private interview about your experiences. The study happens in two phases: first, researchers explore what's happening at these parties and the harms people face; then, they work with participants to develop and refine a new harm reduction model. Your participation helps shape practical strategies to make these settings safer.
